The air conditioner remote control method using the pager network that is currently operating, when the power demand increases for the remote control air conditioner registered for power demand control in the summer when the power usage is increased, By using the pager network to turn the power of the air conditioner on and off (on / off) from the remote is made of a configuration to adjust the power demand in the summer.

However, the summer remote control method using the pager network includes both the advantages of the control area over a large area and the disadvantages of paying the unidirectional control flow and network fee in terms of the control system. There is a problem.

1 is a block diagram schematically illustrating a unidirectional remote air conditioner control system using a conventional wireless call network.

As shown in FIG. 1, the unidirectional remote air conditioner control system 100 using a conventional wireless call network includes an energy management system 101 and a remote load control system connected to the energy management system 101. 102, a wireless call network 105 connected to the remote load control system 102, an air conditioner group unit 106 connected to the wireless call network 105, and the like.

The maximum power generation capacity, the maximum supply capacity, the demand rate, the power reserve rate, etc. Calculate, store, and manage your information.

The remote load control system 102 includes a main control unit 103 and a radio call module 104, etc., the main control unit 103 is a power reserve ratio received from the energy management system 101, etc. The information is analyzed and the control command is transmitted through the wireless call module 104.

In addition, the remote load control system 102 controls the OFF of the plurality of air conditioners 107 to 110 included in the air conditioner group unit 106 by using a control command transmitted through the wireless call network 105. , Periodic control (on / off periodic repetition control), temperature control, and the like, and perform a function of transmitting a periodic signal (Vital Sign) for preventing unauthorized separation and life information.

The air conditioner group unit 106 is composed of a plurality of air conditioners (107 to 110) grouped on the basis of air conditioner capacity, etc., according to the control signal received through the wireless call network 105 of the air conditioners (107 to 110) Changes the set temperature, etc.

For a unidirectional remote control air conditioner control system 100 using a wireless call network as shown in FIG. 1, a "protocol communication protocol for a remote control air conditioner" of patent application No. 2001-4152 (application date: January 30, 2001) Has been disclosed by the applicant.

That is, only the control command is transmitted from the remote load control system 102 to the air conditioner group unit 106, and information such as an operating state or power consumption of the air conditioner is transmitted from the air conditioners 107 to 110 to the remote load control system 102. There is a problem. This problem is to check whether the remote control command transmitted from the remote load control system 102 has been properly transmitted without the administrator visiting the site where the remote control air conditioners 107 to 110 are installed. This causes additional problems that are not possible.

It is made, including.

The communication network formed by using the integrated metering system as described above provides a very efficient system and path as a function of the pager. In addition, since the communication network has a bidirectional characteristic in data flow, the communication network has a structure that satisfies the data flow requirements required by the present invention.

The electronic electricity meter (S7) is made of a structure for installing the indoor unit (HCU) 301 as a device for the link of the control target air conditioner (S6) and the end of the integrated meter system network components for data transmission.

In addition, the inside of the indoor collecting device 301 is made of a structure in which the AP 302 is installed on which the application program for the remote air conditioning control function is installed. That is, the AP 302 includes a remote air conditioner control function in which a stacked board type and an internal antenna or an external antenna 303 for a wireless communication are combined in the integrated power meter for electronic meter reading S7. It is made of a structure to be attached.

The AP 302 includes a PLC communication unit 304, a microcontroller 306, a synchronous serial communication unit 305, a wireless communication unit 309, a DC / DC converter 308, and a main power supply unit 307. It is made, including.

The power supply of the AP 302 is supplied as a DC voltage from the electronic electricity meter S7. In this way, the power supplied from the electronic watt-hour meter S7 to the AP 302 is adjusted to a voltage suitable for operation of the AP 302 through the DC / DC converter 308, which is in turn controlled by the main power supply unit 307. It is made of a structure that is transformed into the voltage required for.

The microcontroller 306 embedded in the AP 302 is equipped with an application program for performing a remote air conditioner control function separately from the basic integrated meter reading function, the control target air conditioner (S6) sent from the remote air conditioner control server (S2) Receives a control command for controlling the data through the data transmission device (IRM) (S4) and relays it to the control target air conditioner (S6), and receives the control result and status information signal input from the control target air conditioner (S6) to transmit data Structure to transmit to device (IRM) 305.

The control target air conditioner (S6) receives a wireless communication data transmitted from the AP (302), the wireless modem 313 responsible for transmitting the control results and status information generated from the control target air conditioner (S6) is It is made of a structure to be attached.

The wireless modem 313 is supplied with a DC voltage from the control target air conditioner S6, and the power supplied to the wireless modem 313 from the control target air conditioner S6 is a DC / DC converter. Through the 314 is adjusted to a voltage suitable for the operation of the wireless modem 313, it is made of a structure that is transformed into a voltage form required for each control unit again through the main power supply unit 315.

The microcontroller 316 embedded in the wireless modem 313 relays a control command received through the AP 302 to the main controller 317 of the control target air conditioner S6, and the control target air conditioner S6. Receives the control result and the status information signal transmitted from the main control unit 317 of the) to the structure to perform the function of transmitting to the AP (302).

The electronic electricity meter S7 installed in the vicinity of the controlled air conditioner S6 is utilized as an access point for providing an effective communication path with the controlled air conditioner S6, and the electronic electricity meter S7 and the controlled air conditioner The data transmission method of S6 is based on the use of specific low power wireless communication, and the communication path from the electronic electricity meter S7 to the remote air conditioner control server S2 is remote using power line communication and high speed data transmission network (HFC). It consists of a structure that utilizes the meter network.

By the above configuration, the operation of the air conditioner remote control apparatus and method using the integrated meter network according to an embodiment of the present invention is as follows.

First, when the control target air conditioner S6 is turned off, the wireless communication unit 309 of the AP 302 attached to the inside of the electronic electricity meter S7 maintains the standby standby state. This is because the current consumed in the electronic watt-hour meter S7 is supplied from the primary side of the power supply, so the minimum consumption must be given the highest priority. As shown in FIG. 7, the wireless communication unit 309 is normally activated (407). This is to minimize the consumption of generated current. To this end, the microcontroller 306 embedded in the AP 302 controls the control of the analog switch 402 for power supply during On (10 ms) Off (1 sec) to periodically control the power of the wireless communication unit 309. 405) to limit the average current consumption to less than 120uA. At the same time, the microcontroller 401 applies power and simultaneously activates the receiver of the wireless communication unit 309, analyzes the signal input from the receiver, and transmits the signal from the control target air conditioner S6 (401) of the beacon frame 410. It is checked whether a synchronization signal (Preamble) 411 has been received (402).

The beacon frame 410 is composed of a synchronization signal (Preamble) 411, a frame header (412), a payload (413), a tail (414) as shown in FIG. The synchronization signal 411 is transmitted in the form of a bit stream 424 composed of information bits for generating synchronization on the receiving side, and the length of the bit is determined by the average consumption current of the receiving side. Therefore, it consists of a total of 400 bits ('0101 ...').

When the microcontroller 306 embedded in the AP 302 receives at least 24 bits of the synchronization signal 41 continuously through the receiver of the wireless communication unit 309, the microcontroller 306 interrupts the power supply and activates the receiver. The remaining bit information of the beacon frame 424 may be received.

The frame header 412 part includes a receiving side ID 421 and a transmitting side ID 420 and includes an operation command 422 and length information 423 of a frame.

The payload 413 has a structure that includes control command arguments and the like of each frame.

Then, the frame check algorithm is applied to the tail 414 for error detection of the frame.

The microcontroller 306 immediately cuts off the power when the power-up time elapses without receiving the synchronization signal 411 of the beacon frame 410 during the period of applying the power of the wireless communication unit 309. If the synchronization signal 411 of the beacon frame 410 is received during the power-on time, the power interruption function is stopped and power is applied for 3 seconds so that at least one beacon frame 410 to be received can be received. The state is maintained so that the receiver of the wireless communication unit 309 can receive all of the beacon frames 410.

If the beacon frame 410 is normally received under the above conditions, the microcontroller 306 maintains the power-on state of the wireless communication unit 309 and generates a keep alive frame to receive the received beacon frame ( The ID 420 of the control target air conditioner included in 410 is analyzed and transmitted to the analyzed control target air conditioner S6 (403). At the same time, the microcontroller 3021 transmits the received information of the controlled air conditioner S6 to the remote air conditioner control server S2 through the facilities of the integrated meter reading network. Upon receiving the beacon information transmitted from the AP 302, the remote air conditioner control server S2 checks the ID and authentication number of the control target air conditioner and records the power-on state of the controlled target air conditioner. When the wireless communication path is generated through the above process, the AP starts a wireless communication relay role between the server and the control target air conditioner.

The wireless modem 313 attached to the control target air conditioner S6 undergoes an initialization process when power is applied while the power of the control target air conditioner S6 is turned off, and then the built-in microcontroller 316 is the main control unit of the air conditioner. Initialization information is transmitted through the serial communication unit 312 connected with 317, and then waits for a control command.

After receiving the initialization information of the wireless modem 313, the main controller 317 of the control target air conditioner S6 transmits the beacon frame generation information through the serial communication unit 312.

The microcontroller 316 of the wireless modem 313 which has received the beacon frame generation information from the main controller 317 of the control target air conditioner S6 generates the beacon frame 410 to generate the beacon frame 410 through the AP (the wireless communication unit 310). 302). The microcontroller 316 of the wireless modem 313 transmits the beacon frame 410 periodically and repeats the transmission until the AP 302 responds to the network access access response of the AP 302. The operation is repeated until a keep alive frame is received.

Thereafter, when the wireless communication path is opened, the communication network path with the remote air conditioner control server S2 and the control target air conditioner S6 is secured. Next, the air conditioner control command, the air conditioner control result, and the status information from the remote air conditioner control server S2 are transmitted and received through an open wireless communication path. Subsequently, the control command from the remote air conditioner control server S2 is performed by a command such as the communication flow chart of FIG. 6, and the process of returning the control result to the remote air conditioner control server S2 is repeated.

When the power of the control target air conditioner (S6) is turned off from the user, the wireless modem 331 attached to the control target air conditioner (S6) detects the case that the main power is turned off through the power circuit monitoring to power the AP 302 Send Off status information. When a response to the reception of the power off status information sent from the AP 302 is received, the wireless modem 313 turns off its own power through the main power unit 315. At this time, even when the main power of the control target air conditioner (S6) is off (Off), the wireless modem 313 may perform the function by receiving power from the auxiliary power supply to transmit the main power cut information to the AP (302). The auxiliary power supply unit may perform a charging function when the main power of the control target air conditioner S6 is applied by adopting a charging circuit.

After receiving a power off command from the wireless modem 313 of the controlled air conditioner S6, the microcontroller 306 of the AP 302 receives power off state information of the controlled air conditioner S6. It generates and sends to the remote air conditioner control server (S2), to switch all the state of the air conditioner control function to the idle (IDLE) state 405, and to switch to the beacon frame 410 receiving mode.
